Abstract: Abstract of the Disclosure Process for eliminating the need for a separate cleaning station in a one-cycle electophotographic document copier machine of the transfer type.  A backcharge corona generator is added to provide an overcharge/backcharge process to obtain the desired level of charge on the photoconductive system prior to exposure of the photoreceptor to the subject.  In that manner, residual toner remaining on the photo-conductor after production of the previous copy is cleaned simultaneously with the development of the succeeding copy.

Abstract: Case 04-4229-U.S. APPLICATION OF NORMAN F. GREEN          NON-SYMMETRICAL OVERLOAD PROTECTION DEVICE FOR DIFFERENTIAL PRESSURE TRANSMITTER               ABSTRACT     A differential pressure to electrical signal transmitter has a pair of barrier diaphragms and a central control diaphragm located between the barrier diaphragms. A first outer chamber on the outside of one barrier diaphragm is pressurized with a first input fluid while a second outer chamber on the outside of the other barrier diaphragm is pressurized with a second input fluid.  A first inner chamber between an inside surface of one of the barrier diaphragms and one side of the control diaphragm is filled by a first substantially incom-pressible fill liquid.  A second inner chamber between an inside surface of the other barrier diaphragm and the other side of the control diaphragm is filled with a second incompressible fill fluid.  The fluid pressure of the two fill fluids are conducted by corresponding fluid filled channels to respective sides of a displacement sensing element to displace the element to produce electrical signal output signals which are dependent upon the difference in pressures of the first and second fill fluids and, hence, upon the pressures of the first and second input fluids.  The control diaphragm is biased into a predetermined position by spring loaded spacers located on corresponding sides of the control diaphragm in the first and second inner chambers respectively.  The spacers have fluid passage holes to permit the fill fluids to reach the control diaphragm.  A first spacer is concentric with the first inner chamber which is smaller in diameter than the second inner chamber whereby the second spacer which is concentric with the second inner chamber overlies the peripheral edge of the first inner chamber to produce a differential input fluid pressure overload response correlated to the non-symmetrical ratio of the directional strength of the displacement sensing element.

Abstract: ABSTRACT In the formation of a metal or metal compound coating on a face of a heated glass substrate during its displacement in a downstream direction through a coating station at which the face is contacted with at least one downwardly  inclined stream of droplets comprising a one or more substances from which the coating is formed, there is a problem in achieving coatings of homogeneous structure and in providing uniform coverage of the substrate.  To help reduce these problems, the droplet stream(s) is or are inclined downwardly towards the substrate in the upstream or downstream direction, and one or more counter-currents of gas is or are caused to flow adjacent the substrate path and towards the front of the droplet stream, and suction force is exerted in exhaust ducting whose entrance is located for drawing gases away from the front of the droplet stream(s) at a higher level.

Abstract: Case 606 Inventor:  Gunter R. Behle BOTTOM OUTLET VALVE OPEN AND CLOSED INDICATOR     ABSTRACT OF THE DISCLOSURE         In accordance with the present invention an open and closed position indicator assembly is provided for use with a bottom operable tank car valve assembly.  An operat-ing shaft for the lading valve extends downwardly through the outlet chamber and includes a connectlon portion at its lower end.  An indicator housing is integrally connected to that portion of the outlet chamber above the connection portion which surrounds the operating shaft.  An indicator member located within the indicator housing is internally threaded and engages an externally threaded portion of the outlet chamber.  The indicator member includes a lower non-round opening which is adopted to be driven by a cooperating non-round portion of the operating shaft. Rotation of the operating shaft with an operating handle will move the lading valve between open and closed positions and will also move the indicator member downwardly to a position below the indicator housing to a position viewable by the operator when the lading vlave is in the open position, and will move the indicator member upwardly to a position within the indicator housing which is not view-able by the operator when the valve is in the closed posit-ion.  In addition the extent to which the indicator member extends below the indicator housing may be used as a measure of the extent to which the lading valve is moved toward the open position.

Abstract: ABSTRACT OF THE DISCLOSURE          A separator assembly for an air intake duct for a turbine device for normally removing particulate matter entrained in the air being introduced to the turbine device through the air duct.  The improved separator assembly com-prises a separator element for removing particulate matter entrained in air passing therethrough which is mounted in the air duct so that at least a section of the separator element is movable between a separating position and a by-pass position. More particularly, the separator element is mounted in the air duct so that when it is in the separ-ating position, substantially all of the air passing through the air duct passes through the separator element and so that when it is in the bypass position, a substan-tial amount of the air passing through the air duct by-passes the separator element. A suitable sensing device is provided for sensing the pressure differential of the air across the separator element in the air duct and a clamping device is provided which normally clamps the separator element in the separating position. The clamping device is actuable to release the separator element from the separ-ating position to allow the separator element to move to the bypass position when the pressure differential sensed by the sensing device is above a predetermined pressure difference.  In this mannter, air flow will be maintained to the turbine, even if the separator element becomes clogged or stopped, thereby preventing a situation in which the turbine might otherwise be starved of sufficient air flow.

Abstract: DIFFERENTIAL PRESSURE GAUGE               Abstract of the Disclosure A differential pressure gauge of the type comprising a controlling magnetic helix device carrying a pressure indicat-ing pointer, the position of which is controlled by a magnet magnetically coupled to same and mounted on the free end of a helically coiled bourdon tube exposed to differential pressures within the gauge and anchored in the gauge housing at its other end for this purpose.  The magnet has a planar pole face paralleling the axis of the helix and defines a magnetic axis that is normal to and intersects the helix axis.  The gauge housing defines an integral one piece pressure wall that separates and physically seals the helix from the magnet and bourdon tube and defines within the gauge housing pressure cavity an operating space within which the magnet and its supporting bourdon tube are mounted and operate.  Between the helix and the magnet the pressure wall is of film dimensions to allow close placement of the magnet and helix relative to each other, and for defining a magnetic flux passing "window"; the pressure wall  is contoured to stress in bending.  The bourdon tube is mounted on a mounting plate or crossmember disposed within the pressure cavity, and the mounting plate is arranged for calibrating the gauge by adjustment of the mounting plate, the bourdon tube it carries, and the magnet, as a unit, toward and away from the helix.          The gauge includes a zero datum and a device for setting the indicating pointer on the zero datum from exteriorly of the gauge, including an adjustment mechanism coupled to the helix and seated on the housing in alignment with the helix axis.
